Hard Disk:
The hard disk is installed in the computer's CPU. It is not pulled out like a floppy. The hard disk is like a box. In the same box, there are 3 to 8 discs one stack on one. Each of these has a track record and a sector. Every disc has a read-write head.
The size of the previous hard disk is now available in very small sizes. Hard disk detection can be much longer than a floppy disk.
Now the markets are available from 20Mb to 80Gb in size. The information that is stored in the computer is in the hard disk. Hard Disk is a part of the electronic part that can worsen it can worsen. Therefore, data on the hard disk can be taken as a backup on a hard disk or on a CD. Moreover, it can be revoked if the data loss is lost.
Now SATA hard disks are available in the market, which transmits data faster than the normal hard disk, and the capacity to store their data is high, hard disk with a capacity greater than 300Gb is available at very low rates.
Floppy Drive Drive (Floppy Drive)
The floppy disk drive (floppy drive) is installed in the computer's CPU, the next part from which the floppy is inserted is seen from the part of the CPU. The floppy drive is given voltage power voltage from SMPS. Floppy disk cable from the motherboard is connected to the floppy drive for contact. 3.5 "floppies are currently available in the market so they get the same size floppy disks. Earlier 5.1 / 2" floppy drives were able to get the 5.1 / 2 "floppy from it to store more information than the current storage capacity. It can be stored in 3.5 "floppy, which is very much like the 1.44 MB size. From Floppy's economic window, Information can be stored from the body of a defective material.This disc contains almost every track. Each of the tracks is divided into several sectors. Information is written by Right Writer or Writer. To insert or read information in the floppy, the floppy is inserted into the drive. Moreover, there is a write-down on a floppy in order to avoid deletion of data. With this help, you can close the data in the floppy medium. But now the use of floppy is decreasing.
CD ROM / Writers:
The moment of the floppy's time has passed and the time has come for the CD. Because this is a hallucination for him. The CD is currently available in less expensive. Apart from Floppy, it is stored in a CD with a more detailed information. Apart from this, floppies can sometimes get damaged due to the fact that their information is destroyed. All of these possibilities are very few on the CD.
More than 700MB of information is stored in the CD. This CD is also made of magnetic materials. The information written on the Cd cannot be truncated. So it is called a ROM. Only rewritable CDs can be written or deleted. A CD ROM drive is required to read data in the CD. This CD ROM drive is mounted in the CPU. It is also out of the CPU as a floppy drive, which means that the same face is seen from the outside and the CD is read from there. The CD ROM drive is given voltage through SMPS. When CD data is read, the lights of the CDROM drive are blinked.
DVD ROM is like a CD-ROM, which has DVD and CD read. CD Writer in CD Writer and CD + DVD is written in DVD Writer. DVD is available in 4GB or 8 GB of capacities. You can run the files, photos, slides in your CD or DVD, or you can run in your DVD or DVD player.
SMPS (SMPS):
Sms Switch Mode Power Supply: - Direct Current (DC) power supply to the computer. He needs electricity to run electronic components of a computer and follow the data instructions. Sms It converts the AC voltage to DC. The cabinet is available in various shapes, styles, and sizes. Get fit. There are two types of SMPS. AT and ATX are in such form.
ATX SMPS is currently available in the market. And they are in much use. Converting AC voltage and supplying to the motherboard and other equipment. SMPS is like a box. The weight of SMPS is light and small in size. It has a trunk which should not be too hot with SMPS. Supply from SMPS to hard disk, CD ROM, floppy drive, and motherboard. Sms If a fuse is an excessive voltage then it becomes damaged. That does not affect the system. The laptop also has an AC adapter that is outside of the system. Notebook's battery maintains the supply of electricity for 2 to 3 hours.
